【 摘 要 】

For the research of the optimized sootblowing strategy, some experiments were set up to analyze the relationship between the time and operation parameters, such as NOx emissions, main steam temperature, reheat steam temperature, desuperheating water, etc. Based on these experiments, the characteristic models of steam temperature which described the maximum variation of steam temperature(ΔT) and the characteristic time of steam temperature(Δτ) were presented according to specific operation of sootblower. All these research can offer some help to optimize the sootblower grouping. Finally, the formulation of sootblowing strategies were studied, then a new strategy considering both NOx emissions and steam temperature was proposed, and it can guide the operation of power plant.
